Android/iOS: When it comes to mobile photo editing applications, there are a lot of apps that offer things like color correction and filters, and few that offer more advanced editing tools. Handy Photo doesn't hold back, adding powerful tools like a clone stamp, photo uncropping, and selective editing features.

The app includes built-in tutorials for a number of different tasks. You can remove people and objects from photos, select a person and move them to another spot, or apply selective filters, similar to Snapseed. While it's no replacement for a desktop version of Photoshop, at $2, it's at least worth considering over the considerably more expensive Photoshop Touch.
